Wall hoods perform the double duty of keeping the air in your kitchen clean, while also helping protect the undersides of your kitchen cabinets from grease buildup and harmful steam. When mounted on the wall, an exhaust hood can be vented through the wall, expelling dirty air outside, though many users choose to simply set their oven hood to filter and recirculate the air. Whatever size wall hood you need, traditional or chimney hood, Abt carries hundreds of models to choose from, including top brands like Broan, Zephyr, & more.
